LLVM-CONFIG(1)
NAME
llvm-config - Print LLVM compilation options
SYNOPSIS
llvm-config option [components...]
DESCRIPTION
llvm-config makes it easier to build applications that use LLVM. It
can print the compiler flags, linker flags and object libraries needed
to link against LLVM.
EXAMPLES
- To link against the JIT:
- g++ `llvm-config --cxxflags` -o HowToUseJIT.o -c HowToUseJIT.cpp
g++ `llvm-config --ldflags` -o HowToUseJIT HowToUseJIT.o \`llvm-config --libs engine bcreader scalaropts`
OPTIONS
- --version
- Print the version number of LLVM.
- -help
- Print a summary of llvm-config arguments.
- --prefix
- Print the installation prefix for LLVM.
- --src-root
- Print the source root from which LLVM was built.
- --obj-root
- Print the object root used to build LLVM.
- --bindir
- Print the installation directory for LLVM binaries.
- --includedir
- Print the installation directory for LLVM headers.
- --libdir
- Print the installation directory for LLVM libraries.
- --cxxflags
- Print the C++ compiler flags needed to use LLVM headers.
- --ldflags
- Print the flags needed to link against LLVM libraries.
- --libs
- Print all the libraries needed to link against the specified LLVM
components, including any dependencies. - --libnames
- Similar to --libs, but prints the bare filenames of the libraries without -l or pathnames. Useful for linking against a not-yetinstalled copy of LLVM.
- --libfiles
- Similar to --libs, but print the full path to each library file. This is useful when creating makefile dependencies, to ensure that a tool is relinked if any library it uses changes.
- --components
- Print all valid component names.
- --targets-built
- Print the component names for all targets supported by this copy of LLVM.
- --build-mode
- Print the build mode used when LLVM was built (e.g. Debug or
Release)
COMPONENTS
To print a list of all available components, run llvm-config
--components. In most cases, components correspond directly to LLVM
libraries. Useful "virtual" components include:
- all Includes all LLVM libaries. The default if no components are
- specified.
- backend
- Includes either a native backend or the C backend.
- engine
- Includes either a native JIT or the bitcode interpreter.
EXIT STATUS
If llvm-config succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
